Thyroid Stimulating Hormone Thyroid Stimulating Hormone

Influence of perinatal factors and sampling methods on TSH and thyroid hormone levels in cord blood.

To evaluate the effect of perinatal factors and sampling methods on thyroid stimulating hormone (TSH) and thyroid hormone levels in cord blood, serum TSH, free thyroxine (FT4) and free triiodothyronine (FT3) concentrations were measured in 124 healthy term neonates. Eighty-eight infants were born in normal vaginal deliveries, 25 were delivered by vacuum extractor and 11 by Cesarean section. The...

Thyroid stimulating hormone levels in cord blood are not influenced by non-thyroidal mothers' diseases.
